` IMPROVEMENT 1N POWER-Looy; PoR WEA'vrNG PILED FABRICS.

The Shedule referred to in these Letters Patent and making part of the same Be it known that I, ERAS'rUs B. BIGnLoW, of Boston, in the county of Suffolk, and State of Massachusetts, have invented certain new and useful Improvements in the VVire-Motiou of Power-Looms for leaving Filed Fabrics; and I do hereby declare lthat the following is a full and exact description thereof', reference b eing had to the accompanying drawings, and to the letters of reference marked thereon.

Figure 1 is a front elevation'of my improvements, with such other parts of the loom as are necessary to exemplify them Figure 2, a right-hand end elevation; and

Figure 3, a plan. Y

My invention is particularly applicable to looms in which a series or optional number oil pile-wires is employed; and one part of it relates to a inode of drawing the pile-wires from the cloth, and another part, to a mode of receiving the. pile-wires from the withdrawingmechanism and inserting them in the shed.

The frame-work of the loom is marked a, the layshaft, 1)and the cam-shaft, c.

The pile-wires are formed with a head, as represented in Figure 4, the wire part being marked d, and the wire head, c. A series of these wires, as they lie in the cloth, is represented in tig. 3,V the position of the cloth being indicated by red lines.

The pile-wire heads c may be held in position, to be acted on by the withdrawing-mechanism herein to be specified, by a wire-box or holder, such as is described in a patent granted to me, the 5th day of May, 1857, and numbered 17,198; but as the wire-box or holder, and the mechanism for carrying the inner ends of the pilewires from the position when they are drawn from the cloth, to the position where they are inserted in the shed, and for guiding them therein, make no part of my present invention, they are not represented in the drawings.

lhe withdrawing-mechanism is. supported and carried by a sliding bar, f, which is moved toward and from the cloth on a guide-bar, y, atiixed Vto the loomtrame.

A withdrawing-lnook, h, by which the pile-wires are drawn ii'om the cloth, is jointed to the sliding bar f, in

lsuch manner as to allow the wit-lidrawing-hook to swing toward and from the heads of the wires in the cloth, the hook being pushed toward-the wire-heads by a spring, fi, and limited in its movement in that direction by a stop-pin,j.

'hcn the withdrawing-llook approaches the cloth, it strikes against the wire-head, on which it is to act, as shown in Figure 5, and when lit eompletesits movement in that direction, it glides over the wire-head, (which is held in position by a wire-box, asibefore explained,) and hooks into the square hole 7.', lformed therein,'and engages with it, as shown in Figure/6.

It will be obvious that the withdrawing-hook, thus engaged with the wire-head, will, when it is moved from the cloth, draw out the wire; but should the loom be stopped during the withdrawing-movement, the wire-head would be likely to escape from. the withdrawing-hook. To prevent this, I combine, with the withdrawing-hook, a supporting-bed, I, and a latchguard, m.

The supporting-bed'preveiits thc wire-head from falling away from the withdrawing-hook, and the latchguard prevents it from escaping laterally.

The supporting-bed projects lfrom and is atiixed to' the sliding bar j, andthe latch-guard is jointed to a projection, fn, extending upward from the sliding bar f, in such manner as to be capable of swinging up and down. j

When the witlxdrawing-mechanism is moved toward thecioth to act on aY pile-Wire, vthe supporting-bed passes directly under the wire-heads, while the latchguard glides upon their rounded ends, as upon a fixed cam, and the witl'idrawin'g-hook engages .with the head of the'wire to be drawn ont, as before explained. r1`hen when it is moved away from the cloth to draw out the pile-wire, the latch-guard, after it leaves the wire-heads,

falls down by its own weight, and causes its depending arm o to latch on to the side ot` the wire-head, as shown in Figure 7 and hold it in position.

As the withdrawing-meelianism approaches the completion of its outward movement, it delivers its wirehead to an inserting carrier, presently to be described, and returns for another wire, the withdrawing-hook, supporting-bed, and latch-guard, being freed from the wire-head by their return movement.

In place of, or inaddition to the supporting-bed l, I sometimes apply a latch-guard to the under edge of the pile-wire head, similar to the latch-guard m, herein described as applied to the upper edge ot' the wire-head, the lower latch-guard being pressed upward bya spring. A front view of the double latch-guard is given in Figure S, and an end view in Figure 9.

'lhe withdrawing-mechanism is moved to and fro on the guide-bar g, to draw out the pile-wires, by a crank, 1, on the cam-shaft c.

The crank 11, through a double-jointed connectingrod, q, and arm lr, oscillatcs a shaft, s, which carries an upright leverarm, t, which is .connected by a link, u, to the sliding bar j', before described, so that each revolution of the crank imparts a reciprocating movement to the withdrawlng-mechanism.

'lhe inserting-carrier, which receives the pile-wires from the withdrawing-meellanism and inserts them in the shed, l. will now describe. It consists of a socket, fc, suitably formed to receive the heads of the pilewires, the face or opening of which is represented in Figure 10. It. is formed in or aflixed to a vibrating statf, r, presently to be described, and has a wing, zr, extending from its rear ride, which serves to guide the wire-heads into the socket, and also to hold the wireheads in position, while the inner ends of the wires are detlected, to bring them to the proper place for insertion in thel shed.

'.lhe vibrating statt' yv has a movement toward and from the cloth, to receive and insert the pile-wires; and, also, a movement tiom and toward the breastbeam, to transfer thc pile-wires from the line where they are withdrawn from the cloth to the posit-ion where they are inserted in the shed. It. is guided and supported by a shaft, y, which oscillatcs in stands s.

lt` vibrates in a slot, a', and is maintained in a proper position, during its vibrations, by a lever-arm, b', acting as a parallel motion, the slot in its lower end plying on a stud, e'.

From the shaft.- y, arms d extend, which severally support the stud c and the axis c' of the lever-arm b. The stati' is viln'ated vby oscillating the axis c', which receives its motion from the `grooved cam f', on the cam-shaft c, the action of the grooved cam f being transmitted to the axis c' by a treadlc, g', doublejointed connecting-rod h', and lever-arm yi.

The shaft i/ is oscillated, to move the upper eml ot' the stati' to which the inserting-carrier is aiiixed, from and toward the breast-helm, by a grooved cam;`f, acting on a lever-arm, 1.", extending from said shaft.

Now, suppose the witlulrawing-mechanism to be armed with a pile-wire, as represented in Figure 12, and about to complete its outward movements, and

suppose, also, tllat the inserting-carrier is in its outer position, and opposite the pile-wire head, it will be obvious that when thewithdrawing-meelianism completes its outward movement, it will draw the outer end oi' the whe-head into the illscrting-carrier, as shown in tigs. 3 and 1l. "l.hen, by means previously explained, the inserting-earricr is moved toward thc lay, to trailsi'er the wire tothe position in which it is to be inserted in the shed. (the inner end ot' the wire being carried back anu guided into thc shed by the usual means,) then toward the cloth, to insert the wire in the shed, and then toward the breastbeam,to bring thc wire to the cloth-forming line, where. the wire-head is held in position by the wire-box, before alluded to. lt then returns for another wire.

'lhe wire-heads are suitably retained in the inserting-cau'icr, while the wires are being inserted, -by a spring, l', atiixed to the vibrating statt' e, which has a projection, m', (see fig. 10,) entering into the socket of the inserting-carrier, and terminating in a spherical face, which engages with a countersunk cavity formed in the side ofthe wire-head.

The spring l allows the spherical face of the projection m to glide over the side of the wire-head when it is drawn into the socket until it enters the countcrsunk cavity, and also allows it to give back when the inserting-carrier is withdrawn from the wire-head, to return fora new wire, the wire-head heilig held in the wirebox by a guard enternganotch, n', in the under side of the wire-head.

The form and construction ot' the mechanism by which my invention is operated maybe greatly vancd, withoutesscntially changing its character; as, for example, instead ot' moving the vibrating staff v in both directions, by a grooved cam, as above described, it may be drawn toward the cloth by a spring, and moved away from it by a single-action ram, by an arrangement represented in Figure 13.

A pulley, marked o', is affixed to the axis c of the lever-arm b', and has -va strap, p', attached to it, one end of which is connected with a spiral spring, q', while the other passes around guidepnllev, Ir', and is con nected with the treadle g'.

From this description it will be seen, that when the. treadle g' is raised by its cam, it willdraw the vibrat ing` statl r away from the cloth; then, when the cam allows the treadles g to descend, the spring q will draw it toward the cloth. v Haring described my invention, and pointed ont same otl the modifications of which it is susceptible, without departing from its distinguishing principles,

What l claim as new therein, and desire to secure by flyetters latent, isl lhe combination, with the withdrawing-hook, which draws the pile-wires from the cloth, ot' a supportingbed, or its equivalent, and a latch-guard, by which the pile-wire heads are prevented from escaping from the withdrawing-hook while the pile-wires are being drawn ont, substantially as specified.

Also, in combination with the witlidrawing-mecham ism herein described, an inserting-carrier, which receives the pile-wire heads from the withdrawiiig-mechanism, and inserts the pile-wire in the shed, when said inserting-carrier is operated by a vibrating statt', having imparted to it a parallel motion, and maintained in a proper position while moving toward and from the cloth, substantially/,as specified.
